Haiti is at serious risk of further devastation from earthquakes in the near future, geologists have warned. Their research, to be published in next month's issue of Nature Geoscience, indicates that not all the geological strain that triggered the original quake in January has been released as had been thought. 
  
 More than 230,000 people died in the magnitude 7.0 quake on 12 January and more than one million were left homeless. Now geologists are warning that Haiti faces the prospect of further devastation. 
  
 "The January earthquake only unloaded a fraction of the seismic energy that has built up over time in Haiti," Eric Calais, a geologist at Purdue University, Indiana, who is also a science adviser for the UN development programme in Haiti, told Nature. "Other earthquakes are therefore inevitable." 
  
 The Haiti quake – which struck at 4.53pm local time and lasted 30 seconds – occurred at the interface of the Caribbean and North American tectonic plates, which are slowly sliding past each other. Seismic strain builds up at certain points where the plates touch and this is abruptly released when they jump position. Port-au-Prince, the capital of Haiti, has twice been destroyed, in 1751 and 1770. 
  
 For the past 10 months, geologists have been investigating a geological fault system on the boundary of the two plates known as the Enriquillo-Plantain Garden. This was thought to be the centre of the quake. However, to their surprise no evidence to support this assumption has been found. 
  
 "This is pretty bizarre," said Roger Bilham, a geologist at the University of Colorado. One explanation, he suggests, is that the surface part of the fault was clamped shut by a complex series of ground slips. "If so, another strong quake could happen any time, right about the January epicentre." 
  
 The Haiti earthquake devastated Port-au-Prince. Buildings destroyed or badly damaged included the presidential palace, the National Assembly building, the cathedral and the main prison, while the list of those killed included the Archbishop of Port-au-Prince, Joseph Serge Miot, the opposition leader, Micha Gaillard, and Hédi Annabi, chief of the United Nations stabilisation mission in Haiti. 
  
 Since then, a major operation to rebuild the city with international help has been launched, as doctors warn that there is a growing risk of a cholera outbreak in refugee camps. 
  
 "What we know hasn't brought us any closer to understanding Haiti's seismic future," Bilham said. "We can only recommend rebuilding Port-au-Prince as safely as money allows." ||||| PORT-AU-PRINCE | 
  
 PORT-AU-PRINCE (Reuters) - Government officials and aid partners in earthquake- and cholera-ravaged Haiti scrambled on Monday to prepare crowded quake survivor camps and coastal towns for a possible hit by a hurricane later this week. 
  
 Tropical Storm Tomas, which is heading westward across the eastern Caribbean sea, is expected to turn north toward Haiti and Dominican Republic by the end of the week, and restrengthen as a hurricane, the U.S. National Hurricane Center said. 
  
 Jamaica also could be impacted, although the precise track of the storm remained uncertain, the forecasters said. 
  
 Tomas now threatens another humanitarian emergency for disaster-prone Haiti, the Western Hemisphere's poorest state. 
  
 Haiti suffered a devastating earthquake in January and is grappling with a cholera epidemic that has killed at least 330 people so far and sickened nearly 5,000 more. 
  
 "This storm is approaching at a time when aid agencies in Haiti are already stretched to the limit," said Nigel Fisher, the humanitarian coordinator for the United Nations in Haiti. 
  
 "The humanitarian challenges involved are among the most complex I've seen in my entire career," Fisher added in a statement. 
  
 As a Category 1 hurricane over the weekend, Tomas battered Barbados, St. Lucia and St. Vincent in the Windward Islands, ripping roofs off homes and knocking down trees and power lines. Insurance experts were estimating damage-linked insurance payouts for the three islands would top $10 million. 
  
 In St. Lucia, the west coast tourist town of Soufriere, the area hardest hit by Tomas as it passed, was cut off by landslides blocking roads and accessible only by sea, the National Emergency Management Organization (NEMO) said. 
  
 A NEMO spokesperson told Reuters emergency services were checking unconfirmed reports that at least five people, and possibly more, were killed in the Soufriere landslides. 
  
 At 5 p.m. on Monday, Tomas was carrying top sustained winds of 45 miles per hour, and was located about 65 miles northeast of Aruba, moving westwards, the Miami-based hurricane center said. 
  
 "Haiti or Jamaica are the most likely targets of Tomas," hurricane expert Jeff Masters of private U.S. forecaster Weather Underground wrote in his blog, citing computer forecast models. 
  
 But he added weather conditions meant the exact track of Tomas remained uncertain, and the storm could still be in the Caribbean a week from now. 
  
 CAMPS SEEN VULNERABLE TO WIND, RAIN 
  
 Haitian officials and aid workers are worried that the powerful winds and torrential rain associated with Tomas will menace more than 1.3 million homeless earthquake survivors living in tent and tarpaulin camps scattered across the hilly capital Port-au-Prince. |||||
Haitian officials and aid workers are scrambling to prepare the devastated country for yet another natural disaster. Tropical Storm Tomas is expected to hit Haiti by the end of the week—and to be a hurricane again by the time it does, Reuters reports. “This storm is approaching at a time when aid agencies are already stretched to their limit,” thanks to the ongoing quake recovery and a cholera outbreak that has killed at least 330 people, one UN official said. As if that weren’t bad enough, scientists believe the country could be in for yet another huge earthquake in the near future. New research published this month indicates that January’s quake “only unloaded a fraction of the seismic energy that has built up” in Haiti, which means more quakes are “inevitable.” The findings are “pretty bizarre,” one geologist tells the Guardian, and they imply that "another strong quake could happen at any time.”
